' The invention which constitutes the subject matter of this applicationrelates to an improved locking mechanism for window sashes, particularlyapplicableto balanced windows of the Austral type. 7 tion has to do withmechanism not only for. latching the sasies in closed position, but alsowith means cooperating with the closthe sashes into closed positionafter having been opened. the invention'is the prowhereby' the shade forthe upper sash may be drawn downwardly into contact with the uppersurface of the meeting rail of the upper sash.

Other objects, advantages and features of construction and operationwill more fully appear from the detailed description below taken inconnection with the accompanying vision of means drawing in 'whi chFigure 1 isa vertical'cross sectional view of an Austral window showingmy invention applied thereto; 7

Figure 2 is an enlarged view of the meeting rails of the'two sashesshowing my mline 22 of Figure 4:; Figure 3 is a section of Figure 4;

Figure 6 is a section taken on .the line 6-6 of Figure 4.. r 7

Referring to the drawings in'detail, the reference numeral 10 designatesa frame in provements in cross section taken on the taken onthe line 3-3top' plan view of my invenwhich'the two sashes 11 and 12 are mount-f ed,the former being provided with sliding pivots at the top and the latterwithsliding pivots at'the bottom. These two sashes are pivotally'connected by balanced arms 13 (only one being illustrated) so that whenone of said sashes is vmoved the other is simultaneously moved with it.The reference numeral 1 1 designates the meeting rail of the lower sash15 the meeting rail of the upper sash. make no claim per se, however, tothe various parts just referred to as they are old and well known in theart.

Upon the meeting rail 15 of the upper sash is secured the keeper platecomprising a base 16, a latch engaging extension 17 55 a member 18provided with a perforation 19 The inven-- to the inner edge e for. theupper sash when:

' with.

a section taken on the line and the reference numeral I dow sashes willbe drawn in which the window closing cord is detachably secured, and theshade guide pulley 20 journaled in the members 21 and-I22- extendingupwardly from the base plate 16.

The base plate 16 and latch engaging means a 17, the member 18 andjournal members 21 and 22 are of unitary or integral construction.v Theouter peripheral surface of the pulley orguide 20 is located inproximity Also the inner journal members :21 and 22 are in a plane 23"of the base plate.16..' edges or surfaces of theor substantially in aplane with said inner edge 23 in consequence of which the shade pulleddownwardly is enabled to contact with the upper surface of the meetingrail 15. f v

Upon the meeting rail 1a "of the lower sash is secured a base membercomprising a base plate 2 1 provided with tending from he inner edgethereof'outwardly beyond the outer edge of the base plate but preferablyAdjacent the inner end of the arm 25 is a guide member 26, preferably apulley, and adjacent its outer end a guide member made integral there- I27 also preferably a pulley. Pivoted about I a horizontal axis and shaft28 of the pulley 26 is a latch member 29 held in latching engagementwith the spring 30. This latch member extends outwardly beyond the baseplate 24: and is propreferably on the s5 latch engaging means 17 "by'means of a vided adjacentits outerend with a perfotion 31 adapted toreceivea cord for disengaging the latch from the latch engaglng means17. Extending upwardly from. the base plate 2 1 is a bearing member 32for. the shaft 28,. the being journaled in the walls of the outward 1yextending arm25.

It will of course be understood that the closing cord passes over theguide pulley other end of said shaft 27 and over the guide pulley 26 and'engages the member 18 of the keeper plate.

it will be readily apparent that the wintowards each other When asufficient pull is given to this cord so as to enable the latch 29 toengage with the latch engaging member 17 to lock the sashes inclosedposition. When it is desired to open or separate the sashes forventilation or other purposes erted upon the outer end of the arm 29against the tension of the spring with 1 a downwardpull is ex 1 theresult that said arm 29 is moved; in

L of one sash provider for attaching a window :plate secured tothemeeting rail of the other 7 for attaching a sash, and means on said aclockwise direction around the shaiit-28 as an aXis' disengaging thesame from the latch engaging member 17.

- From thetoregoingit will seen that I have devised an improved opening,clos ing and; latching mechanism 'for balanced \v1ndoWs,' particularlyuseful Where the Window proper is located out of reach of the operatoras in'the' case of Windows in pubhe schools, gymnasiums, etc.

hat I claim and desire to secure byLetters Patent is:

1. In an improved Window latching mechanism, a keeper secured to themeeting rail closing corch a base sash, and means on said base plate forguid- 'ing said cord comprising anarm extending from the inner edge of,said base plate out- Wardly beyondothe plane of the sash to with meansthereon Whiclrsaid base plate is securech a cordgui-fle member securedto the inner'end ot said arm and in juxtaposition to said keepe, plate,and a cord guide the portion of said arm which projects be yond theplane of the sash attached. I

' '3. In animproved Window 01' one sash provided with means thereon forattaching a Window closing cord, a base member secured to to which it islatching mech- .anism, a keeper secured to the meeting rail platesecured to the meeting rail cf the other sash, for guiding said cordcomprising 0'? ailing from the inner edge of said base plate outwardlybeyond the plane of the sash to Whichsaid base plate secured said armcomprising a top and two side aprons integral with and projectingdownwardly from said top, aqcord guide pulley pivotal ly secured to theaprons at the inner end of said'arm and in juxtaposition to said keeperplate, an'o a cord guide pulley pivotally, secured to the aprons on theportion of said arm which projects beyond the plane of the sash tojwhichit is attached thedistance between said aprons being substantially equalto thewidth of said pulleys- In testimony wliereot l have hereunto setmy hand this 22nd day of WINIER and means on said base plate an arn'rSeptember, 1922.
